Dexamethasone-cyclophosphamide pulse therapy outcomes comparing pemphigus vulgaris and pemphigus foliaceus groups in a Brazilian cohort study

Abstract Background Dexamethasone-cyclophosphamide pulse (DCP) and dexamethasone pulse (DP) have been successfully used to treat pemphigus, but DCP/DP outcomes comparing pemphigus vulgaris (PV) and pemphigus foliaceus (PF) are scarce. Objective To compare DCP/DP outcomes in a Brazilian cohort of PV and PF patients according to demographic and clinical data. Methods Retrospective analytical cohort study, reviewing medical charts of PV and PF patients (for DCP/DP Phases I‒IV consult Pasricha et al.16‒18). Results 37 PV and 41 PF patients non responsive to usual treatments were included similarly for DCP or DP therapy. Disease duration was longer among PF before DCP/DP prescription (p < 0.001); PF required a higher number of monthly pulses to acquire remission in Phase I (median 10 and 6 pulses, respectively; p = 0.005). DCP/DP outcomes were similar in both groups: remission in 37.8% of PV and 34.1% of PF after completed DCP/DP cycles following a median of 13 months (1-56 months follow-up); failure occurred in 13.5% of PV and 14.6% of PF in Phase I; relapse in 13.5% of PV and 12.2% of PF, and dropout in 27% of PV and 24.4% of PF in Phases II to IV. Mild side effects were documented. Study limitations The severity of PV and PF disease was not assessed by score indexes. Conclusions PV and PF patients presented similar DCP/DP outcomes. DCP/DP should be initiated earlier in PF patients due to the longer duration of their disease in order to decrease the number of pulses and the duration of Phase I to acquire remission.

Vogt-Koyanagi-Harada syndrome: a discussion about resistance to corticotherapy / Vogt-Koyanagi-Harada: uma discussão sobre resistência à corticoterapia

ABSTRACT Vogt-Koyanagi-Harada (VKH) syndrome is an inflammatory condition of unknown etiology that can affect the eye. The most common ocular manifestation related to VKH is bilateral diffuse uveitis associated to exudative retinal detachment. Although these patients respond well to steroid pulse therapy, we report a case of a 44-year-old female patient presenting bilateral exudative retinal detachment and clinical diagnosis of VKH, who did not respond to the first cycle of 3-day pulse therapy with methylprednisolone. The exudation was reabsorbed only after a second cycle of steroid therapy.

RESUMO A doença de Vogt-Koyanagi-Harada é inflamatória e de etiologia desconhecida, podendo afetar o olho. A manifestação ocular mais comum relacionada à doença de Vogt-Koyanagi-Harada é a uveíte difusa bilateral associada ao descolamento exsudativo da retina. Embora esses pacientes respondam bem à pulsoterapia com esteroides, relatamos um caso de paciente de 44 anos que apresentou descolamento exsudativo bilateral da retina com diagnóstico clínico de doença de Vogt-Koyanagi-Harada que não respondeu ao primeiro ciclo de pulsoterapia de 3 dias com metilprednisolona. A exsudação apenas reabsorveu após uma segunda rodada de terapia com esteroides.

Corticosteroid associated lupus pancreatitis

SUMMARY The relationship between acute pancreatitis and the administration of glucocorticoids is unclear because most reported cases have been diagnosed with systemic vascular diseases, such as systemic lupus erythematosus, which may be responsible for pancreatitis. A 22-year-old woman with eye involvement of a newly diagnosed systemic lupus erythematosus was admitted to our hospital. Pulse intravenous methylprednisolone therapy was given at 1mg/kg day for 3 days, and oral prednisolone at 40 mg/day thereafter. During pulse steroid therapy, she had abdominal pain, back pain, distention, nausea, and vomiting. Her physical examination was compatible with acute abdomen and peritonitis. Abdomen Computerized Tomography scan revealed diffuse liquid perihepatic and perisplenic area with heterogeneity around the mesentery. Due to the symptoms of acute abdomen, explorative laparotomy was performed. There was diffuse free fluid in the abdomen and edematous changes were observed around the pancreas. Amylase and lipase from intraabdominal fluid were studied and found to be high. The postoperative prednol dose was reduced carefully. On the sixth postoperative day, the drain was removed, and the patient was discharged without any problem. Physicians should keep in mind that acute pancreatitis may also be a cause of differential diagnosis of newly developed abdominal pain in patients receiving pulse steroid therapy with a normal level of serum amylase and lipase.

RESUMO A relação entre pancreatite aguda e a administração de glicocorticoides é incerta pois a maioria dos casos relatados foram diagnosticados com doenças vasculares sistêmicas, como lúpus eritematoso sistêmico, que pode causar pancreatite. Uma paciente de 22 anos com envolvimento ocular e lúpus eritematoso sistêmico recém-diagnosticado foi admitida em nosso hospital. Pulsoterapia intravenosa com metilprednisolona 1mg/kg foi administrada por 3 dias. Depois disso, a paciente foi tratada com prednisolona oral 40 mg/dia. Durante a pulsoterapia com corticoides, a paciente apresentava dor abdominal, dor nas costas, distensão, náusea e vômitos. O exame físico era compatível com quadro de abdome agudo e peritonite. Tomografia computadorizada do abdome revelou líquido difuso na região perihepática e periesplênica, com heterogeneidade ao redor do mesentério. Devido aos sintomas de abdome agudo, foi realizada laparotomia exploradora. Havia líquido livre difuso no abdome e alterações edematosas foram observadas em torno do pâncreas. A amilase e lipase do líquido intra-abdominal foram analisadas e consideradas elevadas. A dose pós-operatória de prednol foi reduzida com cuidado. No sexto dia de pós-operatório, o dreno foi retirado, e a paciente recebeu alta sem qualquer problema. Médicos devem lembrar que a pancreatite aguda também pode ser uma causa de diagnóstico diferencial para dor abdominal recém-desenvolvida em pacientes recebendo pulsoterapia com corticoides e com níveis normais de amilase e lipase séricas.

Clinical effect of low-frequency electrical pulse therapy combined with α-lipoic acid on diabetic gastroparesis in elderly patients with type 2 diabetes / 中华老年医学杂志

Objective To investigate the clinical effect of low frequency electrical pulse therapy combined with α-lipoic acid on diabetic gastroparesis in elderly patients with type 2 diabetes.Methods A total of 65 patients diagnosed as diabetic gastroparesis were selected from our hospital and divided into three groups according to random number table:the control group(n =23,the α-lipoic acid treatment),the conventional treatment group (n =16),and the experimental group (n =26,treating with α-lipoic acid combined with low-frequency electrical pulse therapy).All patients received the conventional diabetic therapy.Clinical effects,gastric emptying rate and serum gastrin(GAS) and fasting blood glucose levels were compared before versus after treatment among the three groups.Results The cure and total effective rates were higher in the experimental group than in the control group [46.15％ (12 cases) vs.30.43％ (7 cases),80.76％ (20 cases) vs.65.21％ (15 cases),x2 =0.867,P＜0.05].There were significant differences in gastric emptying rate,serum gastrin and fasting plasma glucose levels among the 3 treatment groups before versus after treatment.And the gastric emptying rate and serum gastrin level were better improved in the experimental groups compared with the conventional treatment and control groups.Conclusions The low-frequency electrical pulse therapy combined with α-lipoic acid has a significant clinical efficacy,which can improve clinical effects,promote gastric emptying,decrease fasting plasma glucose levels in elderly patients with type 2 diabetes.

Cardiogenic shock due to citomegalovirus myocarditis: successful clinical treatment / Choque cardiogênico devido à miocardite por citomegalovírus: terapêutica clínica com sucesso

OBJECTIVE: Cytomegalovirus (CMV) systemic disease and myocarditis in healthy persons is infrequently reported in the literature, although in increasing numbers in recent years. The importance of the recognition of the syndrome that usually has an initial picture of a mononucleosis like infection in an otherwise healthy person, is the available therapeutic agent, ganciclovir, that can cure the infectious disease. METHODS: We analyzed the clinical result of pulsotherapy with steroids in a patient with CMV myocarditis after 7 days of etiological treatment, with ganciclovir, intravenous vasodilators, and the conventional treatment for congestive heart failure. RESULTS: The clinical condition of the patient improved accordingly to the better function of the left ventricle, and the ganciclovir was kept for 21 days, most of it in an out patient basis. The patient was dismissed from the hospital, with normal myocardial function. CONCLUSION: Potentially curable forms of myocarditis, like M pneumoniae and CMV, for example, can have an initial disproportionate aggression to the myocardium, by the acute inflammatory reaction, that can by itself make worse the damage to the LV function. In our opinion, the blockade of this process by pulsotherapy with steroids can help in the treatment of these patients. We understand that the different scenario of immunosuppressive treatments for the possible auto immunity of the more chronic forms of the presumably post viral cardiomyopathy has been in dispute in the literature, and has stolen the focus from the truly acute cases.

OBJETIVO: Doença sistêmica por citomegalovírus (CMV) com miocardite em pessoas saudáveis é raramente referida na literatura, apesar de em maior número em anos recentes. A importância do reconhecimento da síndrome, que usualmente tem um quadro inicial "mononucleosis like" em uma pessoa sadia é a disponibilidade do agente terapêutico ganciclovir, que pode curar a infecção. MÉTODOS: Nós analisamos o resultado da pulsoterapia com esteróides em um paciente com miocardite por CMV, após 7 dias de tratamento etiológico com ganciclovir, vasodilatadores intravenosos e o tratamento convencional para insuficiência cardíaca congestiva. RESULTADOS: A condição clínica do paciente melhorou com a melhor função do ventrículo esquerdo e o ganciclovir foi mantido por 21 dias após alta hospitalar.A função miocárdica retornou ao normal. CONCLUSÃO: Formas curáveis de miocardites como M pneumonia e CMV, por exemplo, podem ter uma agressão grave ao miocárdio por uma ação inflamatória que pode piorar a função cardíaca. Em nossa opinião, o bloqueio deste processo pela pulsoterapia com esteróides pode auxiliar no tratamento destes pacientes. Entendemos que existe um cenário diferente de tratamento com imunossupressores para possível agressão auto-imune das formas mais crônicas de cardiomiopatias dilatadas e isso está em disputa na literatura, talvez mudando o foco dos casos realmente agudos.
