Unrecognized Primary Hypothyroidism As a Possible Cause of Hyperreactio Luteinalis.

Hyperreactio luteinalis (HRL) is characterised by benign enlargement of ovaries in pregnancy associated with hyperandrogenism. A 19-year-old primigravida presented with breathlessness, abdominal distension and vomiting in the thirteenth week of gestation. Abdominal examination revealed distension of abdomen disproportionate to the gestational age. Ultrasound was suggestive of bilaterally enlarged multicystic ovaries with a characteristic "spoke-wheel" pattern and a diagnosis of HRL was made. Laboratory investigations revealed primary hypothyroidism and elevated testosterone. She was initiated on levothyroxine therapy. Her respiratory distress worsened on the third day of admission for which she underwent emergency laparotomy with cyst aspiration. Thyroid function tests normalized within six weeks after the initiation of therapy and remained normal for the remainder of pregnancy. Serum testosterone levels returned to normal six weeks postpartum. The elevated thyroid-stimulating hormone levels could have contributed to development of HRL by cross-reacting with human chorionic gonadotropin and follicle-stimulating hormone receptors. Hyperandrogenism and ovarian enlargement regresses with levothyroxine therapy.

Neonatal diabetes mellitus: remission induced by novel therapy.

A female child with deafness was diagnosed to have neonatal diabetes mellitus at the age of 6 months, on routine evaluation prior to cochlear implant surgery. She presented to us at 11 months of age with diabetic ketoacidosis due to an intercurrent febrile illness. Her haematological parameters showed megaloblastic anaemia and thrombocytopenia. Therefore a possibility of Thiamine Responsive Megaloblastic Anaemia (TRMA) syndrome was considered. She was empirically treated with parenteral thiamine hydrochloride (Hcl). Subsequently, due to the unavailability of pharmacological preparation of oral thiamine Hcl in a recommended dose she was treated with benfotiamine. She had a sustained improvement in all her haematological parameters on oral benfotiamine. The insulin requirement progressively reduced and she is currently in remission for last 2 years. The genetic analysis confirmed the diagnosis of TRMA syndrome. Thus benfotiamine can be considered a new treatment option in management of TRMA syndrome.

Hypothyroidism and Depression: Are Cytokines the Link?

CONTEXT: Primary hypothyroidism has been thought of as an inflammatory condition characterized by raised levels of cytokines such as C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α). Depression is also well known to occur in hypothyroidism. Depression is also characterized by elevated inflammatory cytokines. We planned to study whether cytokines play an important part in linking these two conditions. OBJECTIVES: (1) To know the prevalence of depression in overt hypothyroidism due to autoimmune thyroid disease. (2) To correlate the levels of inflammatory markers with the occurrence of depression. (3) To study the effect of levothyroxine on inflammatory markers and depression. MATERIALS AND METHODS: In this longitudinal, case-controlled study, 33 patients with autoimmune hypothyroidism (thyroid-stimulating hormone >10 uIU/ml) were included with 33 age-, sex-, and body max index-matched healthy controls. Individuals were tested for Serum TNF-α, IL-6, high-sensitivity-CRP (hs-CRP). They were assessed for depression using Montgomery Asberg Depression Rating Scale (MADRS) and World Health Organization Quality of Life (QOL) Scale. Patients received L Thyroxine titrated to achieve euthyroidism and were reassessed for inflammatory markers and cognitive dysfunction. RESULTS: Nineteen patients (57%) had mild to moderate depression (MADRS >11). After 6 months of treatment, eight patients (42%) had remission of depression with significant improvement in QOL scores (P < 0.05). TNF-α, IL-6, and hs-CRP were significantly elevated in patients compared with controls and reduced with therapy but did not reach baseline as controls. The change in inflammatory markers correlated with improvement in QOL scores in social and environmental domains (P < 0.01). CONCLUSIONS: Primary autoimmune hypothyroidism is an inflammatory state characterized by elevated cytokines which decline with LT4 therapy. It is associated with depression and poor quality of life. Treatment of hypothyroidism results in alleviation of depression in the majority of patients. Similarly, patients with mild to moderate depression should be tested for hypothyroidism as simple treatment may ameliorate their depression and improves MADRS score and QOL.

Pituitary dysfunction in traumatic brain injury: Is evaluation in the acute phase worthwhile?

INTRODUCTION: Traumatic brain injury (TBI) is an under-recognized cause of hypopituitarism. According to recent data, it could be more frequent than previously known. However, there is a scarcity of data in Indian population. AIMS: The main aim of the study was to determine the prevalence of pituitary hormone deficiencies in the acute phase of TBI. The secondary objectives were to correlate the severity of trauma with basal hormone levels and to determine whether initial hormone deficiencies predict mortality. SUBJECTS AND METHODS: Forty-nine TBI patients (41 men and 8 women) were included in this study. Pituitary functions were evaluated within 24 h of admission. RESULTS: Gonadotropin deficiency was found in 65.3% patient while 46.9% had low insulin-like growth factor-1, 12.24% had cortisol level <7 mcg/dl. Cortisol and prolactin level were positively correlated with the severity of TBI suggestive of stress response. Free triiodothyronine (fT3) and free thyroxine were significantly lower in patients with increasing severity of tuberculosis. Logistic regression analysis revealed that mortality after TBI was unrelated to the basal pituitary hormone levels except low T3 level, which was found to be positively related to mortality. CONCLUSIONS: Pituitary dysfunction is common after TBI and the most commonly affected axes are growth hormone and gonadotropin axis. Low fT3 correlates best with mortality. During the acute phase of TBI, at least an assessment of cortisol is vital as undetected cortisol deficiency can be life-threatening.

A case of hypersensitivity to soluble and isophane insulins but not to insulin glargine.

Insulin is an important agent for the treatment of diabetes mellitus (DM). Allergic reactions to insulin therapy, although rare, have been evident since animal insulin became available for the treatment of DM in 1922. Hypersensitivity to insulin has considerably been reduced with the introduction of human insulin produced by recombinant deoxyribonucleic acid technology. Here, we present a case of Type 2 DM who demonstrated immediate (Type 1) hypersensitivity reaction on the sites of subcutaneous injection of soluble and isophane insulin but insulin glargine was tolerated well and provided good glycemic control.

Asymmetrical Ovarian Enlargement: Caught Timely Before the Cut!

BACKGROUND: Van Wyk-Grumbach syndrome is a rare complication of prolonged untreated primary hypothyroidism characterized by precocious puberty and enlarged multicystic ovaries. High index of suspicion and timely diagnosis can prevent unnecessary surgical procedures because this condition can be reversed with thyroid hormone supplementation. CASE: A 12-year-old girl underwent abdominal ultrasonography for recurrent abdominal pain, which showed bilateral asymmetrical enlargement of ovaries. Ovarian tumor markers were negative. Subsequent evaluation revealed severe hypothyroidism. Patient was started on levothyroxine and both ovaries showed regression to normal volume within 1 year of normalizing thyroid function tests. SUMMARY AND CONCLUSION: Prompt and adequate medical management with levothyroxine can completely reverse ovarian enlargement associated with hypothyroidism.

Curious case of missing (A) in coeliac disease with type 1 diabetes mellitus.

Coeliac screening in type 1 diabetes mellitus (T1DM) is universally recommended, but not all authorities recommend serum IgA estimation before using an IgA-based test. We report a case of T1DM with poor glycaemic control and recurrent episodes of hypoglycaemias and diabetic ketoacidosis (DKA). Recurrent oromucosal and respiratory infections further complicated the course of illness, resulting in the increasing proneness to DKA. The patient was screened for coeliac disease but the IgA-based screening test was negative (IgA tissue transglutaminase) due to the low IgA level, whereas the IgG antigliadin was positive. The patient benefited from initiation of a gluten-free diet.
